The truth? While research is limited, there’s nothing to suggest that deer antler velvet (or deer antler spray in the supplement form) actually does what it claims. In fact, there are two published studies (in real scientific journals, you can see them here and here) that suggest deer antler velvet does not (I repeat, does not) even elicit a hormonal response. What’s more, it also did not increase muscular strength or aerobic power.
The latest and greatest performance enhancer, if you've been living under a rock, is deer antler velvet. On the surface, it seems like it could make sense. The coating on the antlers of young male deer that contribute to the growth of that part of their body could help athletes. First, the NFL prohibited Oakland Raiders coach Hue Jackson from endorsing it. Now, according to SI.com, Major League Baseball is warning players about using it.

Shake well before use. As a dietary supplement, spray 2 times under tongue, 3 times per day. Hold the liquid under your tongue without swallowing for 20 seconds. This allows the formula to penetrate through your endocrine glands. Then the active molecules are then released directly into your bloodstream.

A systemic review on human interventions[25] makes note of a study conducted on patients of osteoarthritis (Edelman et al. 2000; cannot be located online) which found improvements in joint pain symptoms relative to baseline in the Velvet Antler group and not placebo, although a lack of information on blinding and randomization precludes results that can be drawn from this study.

One of the leading companies in the world that manufacturers deer antler spray is called Nutronics Labs. According to information posted on their website, they have been making deer antler supplements for two decades. They state that their deer antler products range in concentration/strength from about 25,000ng (nanograms)–200,000ng of IGF-1. According to studies done by Nutronics Labs, deer antler powders appear to be less concentrated with IGF-1. They also may be poorly absorbed compared to deer antler extract.

"This mountain bike loop that I do almost everyday usually takes 48-50 minutes. After a few weeks of Antler Farms®, I saw that number continually go down. I am at basically an average of 4 minutes shaven off every time that I do that loop. Faster recovery also. I have more energy later on in the afternoon. Just all around really good results. Good stuff. Highly recommend it."*
Deer antler velvet can play a pivotal role in helping to not only relieve the symptoms of diseases that affect joints, such as osteoarthritis, they can possibly eliminate them entirely. The way it may do this is through the introduction of chondroitin sulfate and glucosamine sulfate into the body. Both of these compounds are abundant in deer antler velvet.
